Ok
I figured out that when I post an image, wordpress makes a new folder: wordpress/wp-content/uploads/2008/11
while it should go to:
wp-content/uploads/2008/11
I installed wordpress in my root folder. How and where can I change the posting codes so that all uploaded images an so on are going to:
wp-content/uploads/2008/11
and that there url-tag is https://BLOG/wp-content/uploads/2008/11/PICTURE.jpg
not
https://BLOG/wordpress/wp-content/uploads/2008/11/PICTURE.jpg
